Revert "net: fix cpu_max_bits_warn() usage in netif_attrmask_next{,_and}"
This reverts commit 854701ba4c39afae2362ba19a580c461cb183e4f. We have more violations around, which leads to: WARNING: CPU: 2 PID: 1 at include/linux/cpumask.h:110 __netif_set_xps_queue+0x14e/0x770 Let's back this out and retry with a larger clean up in -next. Fixes: 854701ba4c39 ("net: fix cpu_max_bits_warn() usage in netif_attrmask_next{,_and}") Link: https://lore.kernel.org/all/20221014030459.3272206-2-guoren@kernel.org/ Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
